Hi ALL,
I am using Bering v1.2 and want to remotely access hosts in the private loc
and dmz.
I have a single public dynamic IP address to my firewall which is
mydomain.dyns.cx.
I added the followings in /etc/shorewall/rules to try it out:
ACTION SOURCE DESTINATION PROTOCOL PORT
DNAT net dmz:192.168.2.1:22 tcp
1022
When I issued "ssh mydomain.dyns.cx -p 1022" from my Linux computer outside
of
the firewall, I got the following errors:
WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
It is possible that the RSA host key has just been changed.
I know what has happened. The "ssh command" was forwarded to the private
host-192.168.2.1 and the host passed its RSA host key to my computer. My
computer thinks it is from my firewall-mydomain.dyns.cx but it has different
RSA host key in the key database. If I issued "ssh mydomain.dyns.cx"
without
"-p 1022", I can log in to my firewall with no error.
Please point me how to remotely access hosts behind firewall.
Thanks & regards,
Jimmy
